QUESTIONS?34
Western Area Power AdministrationTransmission Infrastructure ProgramPresented to: BLM Webinar35
TIP PROGRAM OVERVIEWImplement Title III Hoover Power Plant Act 1984(under American Recovery and Reinvestment Act)Borrowing authority of $3.25 billionIdentify, prioritize and participate in the study, facilitation,financing, planning, operating, maintaining, and construction ofnew or upgraded transmission facilities36
TIP MILESTONES• Feb 2009: Western receives TIP borrowing authority from congress• March 2009: Western published a “Notice of Availability of Request for Interest”in Federal Register• April 2009: Western chartered a Sr Mgt and Transmission Planning team toevaluate over 200 statements of interest from potential project sponsors.• Oct 2009: TIP names Program Manager and begins staffing• TIP is transitioning from start up phase to permanent phase• TIP remains open to new solicitations from Project developers.37
TIP FutureTIP OptimizationBased on Continuous Improvement• Evaluate the Program project development process• Evaluate existing criteria for screening and prioritizing potentialProgram projects• Increase the transparency of the vetting process for potentialProgram projects and• Improve communications with Program applicants38
TIP PROGRAM PRINCIPLES• Projects must have one terminus within area served by Western• Deliver, or facilitate the delivery of, power generated by renewable energyresources to be constructed or reasonably expected to be constructed• Encourage broad-based participation• Uses Project revenue as the only source of revenue for:ooRepayment of loan for projectPayment of ancillary service and O&M expenses• Maintain controls for accounting and repayment - projects under this authorityare separate and distinct• Ensure project beneficiaries repay project cost• Must be in the Public Interest• Must not impair system reliability or statutory obligations• Have reasonable expectation of repayment of principal and interest of Treasuryloan and associated project costs on a stand alone basis – costs cannot beintegrated into existing projects• Use a public process to set rates for new facilities• Must independently obtain and arrange for the delivery of generation-relatedancillary services39
PROJECT SELECTION CRITERIAProjects under consideration for TIP funding must:• Facilitate the delivery to market of power generated by renewable resourcesconstructed or reasonably expected to be constructed.• Have at least one terminus located within Western’s service territory.In addition, project evaluation includes feasibility of developing a project that meets thefollowing criteria:• Provides economic developmental benefits, including an estimate of how many,the type, how fast, and where in the country jobs are created.• Gives priority to projects that satisfy Western’s Open Access Transmission Tariff(OATT) or related requests.• Addresses the technical merits and feasibility of a project.• Financial stability and capability of all potential project partners.• Project readiness (e.g., permitting, local, state and/or regional approval).• Project partners’ participation in a region-wide interconnection-wide planninggroup or forum.40
TIP PROJECT MODELS• Financier model• Construction financing• Construction – Long-term financing• Western owns capacity• Example Project – Montana Alberta Tie Limited (MATL)• Public-Private Partnership model• Partnership with Merchant Transmission Developer• Western uses borrowing authority to finance ownership in Project• Example Project - TransWest Express Transmission Project (TWE)• Western internal transmission projects• Partnership with Western Regional office to add or upgrade neededtransmission identified typically through 10-year planning process.• Example Project - Electrical District 5-Palo Verde Hub Project (ED5-PVH)41
NEGOTIATING WITH DEVELOPERS• Upon selection of SOI, Project Developers favoring Advanced FundingAgreements.• TIP brings the following to the transaction:• Siting, Scoping and Permitting expertise for Environmental processapprovals• WECC path rating expertise in terms of managing studies and process• Experience with Interconnection Agreements• Design expertise for transmission lines and sub-stations• Construction management and Quality Assurance for EPC• Financial structuring and project financing• Operations and maintenance capability• TIP Borrowing authority• Experience with Regulatory issues42

UNDERWRITING REQUIREMENTS• A solid business plan and Project operating plan• Financing and commercially-sound project producing adequate cash-flow to:• Pay all operational costs• Service all debt• Provide owners with reasonable rate of return• Track record of success on similar projects44
WESTERN CERTIFICATIONFinally, Western’s Administrator must certify, prior to borrowing funds fromTreasury, that each project:• Public interest nexus• No adverse impact to system reliability or operations, or other statutoryobligations.• Reasonable expectation that the project will generate enoughtransmission service revenue to repay the principal investment; alloperating costs, including overhead; and the accrued interest by theend of the project’s service life.45

Overview of TransmissionPlanningAnders JohnsonBonneville Power AdministrationLong Term Planning47
Basics of Electric Transmission• Alternating Current (AC) vs.Direct Current (DC)• Generation and load mustalways be balanced• Higher voltages used to movepower long distances• AC flows are closelymonitored but difficult toprecisely controlGeneratorTransformerSubstationTransmissionLineSubstationTransformerLoad48
Drivers for New Transmission• Load Growth• New generators– Renewables– Dispatchable capacity• Changes in asset utilization– Generator retirements (High emission coal)– Oversupply in some areas vs. shortages in others• Open Access Transmission Tariff (OATT)requests49
Transmission Planning Considerations• NERC/WECC Transmission Planning Standards– Deterministic: System must withstand all crediblesingle and common mode contingencies withoutviolating performance requirements– Thermal overload, voltage stability, transient stability• Integrated Resource Planning– Probabilistic: Must have enough transmission capacityto deliver generation to reduce loss of load probability– Production cost analysis– Transmission congestion increases cost to customers50
PExample: Line OutageBeforeAfterGenerator PTransformerSubstation½ P½ PTransmissionLinesPSubstationPTransformerPLoad51
Capacity Increase Options• Incremental upgrades: Push more power throughexisting lines– Substation equipment (capacitors, transformers,circuit breakers)– Increased line rating (increase clearance to ground,replace conductor– Control actions• Build a new line– Sometimes the only technically feasible option– Rebuild existing line to higher capacity, build next toexisting corridor, or build in new corridor– Lumpy52
Additional Considerations• Is project feasible to permit?• Available Transfer Capacity– Commercial allocation of capacity– Firm vs. Non-firm– Need capacity all the way from generation to load, notjust across monitored elements of a path• “Too Big to Fail” Problem– Must plan for outages of double circuit, adjacentcircuit, and HVDC lines– Double circuit does not always provide double theusable transfer capacity as single circuit53
